is it the sound effect thing for 8-channel audio? i have that too. however i didn't even bother with it. i slapped in my SB Live! mp3+ because integrated audio blows on any mobo. it eats away at CPU cycles. i'd rather offload it.
buy a sound card, uninstal your sound drivers, disable your integrated audio in the BIOS, shove the new one into the pci slot, plug in the CD-In connector from your CD or DVD drive, and install the new drivers. eureka! not only do you not have to bother with Sound Effect, but your sound has been offloaded which equals better performance!
if you do that, i can almost garantee that you won't have anymore sound problems.
